PS222L - 3-Channel Secondary Monitoring IC

General Description

PS222L is specially designed for switching power supply system.

Four important functions of PS222L are the following: over-voltage protection, over-current protection, under-voltage protection and power good signal generating.

Key Features

  • Over/Under-voltage protection and lock out.
  • Over-current protection and lock out.
  • Fault protection output with open drain output stage.
  • Open drain power good output signal for power good input.
  • Built-in 300mS power good delay.
  • AC on 75mS delay for UV/OC protection.
  • 38mS PSON/ control de-bounce.
  • 14uS de-bounce for noise immunity.
  • Wide power supply range (4.2V~16V).
  • Special care for AC power off 3-Channel S.
